Energy Review Physical Science
The Equations! • Kinetic Energy = • Gravitational Potential Energy = m g h
Conservation of Energy! • Important Equation • Energy can be neither created nor destroyed but only conserved.
Common Forms of Energy • Potential and Kinetic (aka mechanical) • Thermal • Chemical • Electrical (kind of) • Electromagnetic • Nuclear
Methods of Energy Production • Nonrenewable (fossil fuels, natural gas, etc.) • Hydroelectric Plants • Geothermal Plants
Methods Cont. • Solar Cells and Panels • Wind Turbines!
Ideal System (aka a perfect world) • Energy is not lost to friction or leaking. • In short energy is conserved and perpetual motion works
Real World • Energy is lost to friction • Energy is lost to the production of other forms in conversion processes (such as sound and heat) • Energy is still conserved just we can convert 100% of it into the intended form
